Algarve Bird?

Many Egrrets and Storks in the Castro Marim area, only seen one of these tho.
Can anyone tell me what it is pls :conf40:

Looks like a first winter Little Egret Philip.

Well have had time to search and i now think its a Great White Heron.

Can't find any references to that bird Philip, although some call the great White Egret that name. The only thing is that the great white Egret, doesn't have a dark bill.
